MEANS FR REMOVABLY SUBPORTING MOP-WRINGING MEGHANISMS.

Specification of Letters Patent.

Patented Nov. du, 1h20.

Application filed September 5, 1919. Serial No. 321,832.

Mop-wringers generally include movable elements located above the liquid contents 'ot the pail and means located external of the pail tor moving these elements into and out of wringing position, such external means being operated by a toot ot the operator whose hands are engaged in manipulating the mop. @wing to the iact that wringing the mop practically requires that it be drawn upwardly through the wringingineens in order that the liquid wrung from the mop may return to the pail contents, it is ossential that the mechanism he held against upward movement during the upward-dra'wing o t the mop, and to providethis result it is the general practice to liredly secure the mechanism to the pail itseli1 in order to pren vent relative movement of pail and mechanism during this operation.

These facts have resulted in the use generally ofwooden-containers or pails lor the liquid, permitting a more ready vsecuring oi thepail and mechanism together aswell as `providing a more substantial connection than is made possible by attempting to rivet the mechanism to a sheetmetal container, the rough conditions of service tending to break down such connections. t

The present invention is designed to pro vide an arrangement by which the wringing mechanism and pail are firmly held in proper relation during the wringing operation, but in such manner as to prevent the practice ot dragging the pail by the mop. This is obtained by practically retaining the pail and mechanism as independent elements with no direct and positive connection between them but with the wringer 'structure so `formed `that the pail forms a support for the structure during operation. As a result, any attempt at dragging the pail overthe floor will result in separating the pail from the mechanism and generally upset the pail, the arrangement being such, however, as will permit the pail and mechanism to be shiited it the operator raises them bodily by the pail handle and carries the combination to the new point. Obviously, the necessity for raising the pail taires it out ot contact with the floor and thus eliminates the wear on the pail heretofore caused by the dragging operation. This enables the use of sheet metal pails, it' desired, and practically limits the life oi2 the pail only by the deteriorating action of the liquid content. rind since the entire mechanism is bodily removable with no material ditiiculty, the pail itself can be readily cleansed and kept clean, the entire interior being exposed by removal oi the mechanism.`

To these and other ends, therefore, the nature of which will be readily understood as the invention is hereinafter disclosed, said. invention consists in the improved cons* 1uction and combination of parte, .hereinafter more fully described, illustrated in the`accompanying drawings, and more particularly pointed out in the appended claims.

lfn the accompanying drawings, in which similar reference characters indicate similar parts in each oi' the views,-

Figure` llis a perspective view showing one way in which the present invention may be carried out, the wringing mechanism `shown being one commonly employed commercially.

Fig. 2 is a vertical sectional view taken through the removable structure, the pail being shown in dotted lines, the parts being shown in position for active service.

Fig. 3 is a top plan view of the removable portion shown in Fig. l, the pail being illustrated in dotted lines.

Fig. 4 is a view in elevation.

In the drawingsAindicates generally th structure oi a well-known form" oi mopwringing mechanism, the structure employing a frame a* in which is lxedly positioned a pair of rolls a and a movable roll a', the latter being moved toward and trom rolls a by the operation of a toot member orlever o? through the operation ot a number oi connections arranged to translate the up and down pivotalmovements of lever a2 external 0i` the pail, into horizontal reciprocating movements of roll 'o' internal of the pail above the liquid content of the latter; in

`anism within the pail in use.

some cases ,the connections are such that downward movement of the lever straightens out a toggle connection in such manner as to automaticallyV loclr the parts in closed position, but it is. generally required ythat the operator 'produce the pressure by retaining his foot upon the lever, this additionally acting to retain the pail on the iioor during the upward movement of the mop.

1n the commercial 'form heretofore employed, trame ax is generally secured to the inner race oiC Jhe pail, lever f2 being carried by a suitable support secured externally of the pail, the operating connections extending overl the ltop of the pail wall.

1nY the drawings, the pail is indicated at and, for the present invention car 1ies the usual handle or bail b, the pail beiiigol the usual commercial type usua'ole any desired purpose, I

"fi he changes made will now be described.

As seen in the drawings.y this member 10 when in position lies adjacent the inner periphery at the t 3- ot the `paihand may act in the nature oiA i centering or positioning` structure for the mechanism to retain the latter from shitting freely about within the pail. V

.11 indicates supporting member external of the pail and to which the lever and its support are secured,as showinmc i ber'11 being platelilre in form and preferably having a vertical length.V extendi from adjacent the top to the bottom or afijacent the bottom ot the pail, the member being curved somewhat transversely oi? such length. As shown in Fig. 2, member n ed not closely tit the exterior tace orn the pail and may be of any preferred coniiguration. thatshown having relatively wide top and narrow bottom, the top width permitting the connections. 12V between members 10 and 1-1to be spaced apart a material distancepreferably suiiicient to reduce liability oit rocking of the internal portion of the mech- Connections 152V may-as shown in the drawings-be formed integral with member 11 and be bolted-or otherwise secured to member 10;

obviously, connections 12 may be in the form of separate straps with the outer ends secured to member 1- this. being an obvious change.` VWhere connections 12 are integral with member 11, member 10 need not extend throughout `the complete circularvform, member 11 completing the annular formation to prevent memberv 10 from tend- Vmember 10 opposite connections A1Q,`members 1d projecting outwardly over the top of the pail so as to locate the pivot points external of the pail.

1n operative position, member 13 extends downwardly, practically into contact with the floor, forming a member on which the operator can place one foot while depress ing lever a2 at the other side ot the pailW members 1d may or may not contact with the top of the pail. lilith member 13 held in this position and lever `u? depressed the wringing mechanism will be firmly anchored in such way as not to place any pressures on the pail in directions tending to disturb its position, thus permitting` the usual mopwringing operation as at present.

Should, however, it be desired to shift the pail trom one position to-another, it will be necessary to gi tsp handle and raise the pail-and the wringing mechanism in position thereon-trom the floor. since the pail is not of suiiicient vertical length to permit its being dragged, with the operator walliing upright and a stooping` position is. uncomfortable-especially in the presence of the weight of the mechanism. To attempt to grip the mop in position and dragl the combination simply results in moving` the mechanism upward within the pail to a point where its further movement laterally will upset the pail.,v there being no actual connection between the mechanism and the body of the pail.

To remove the mechanism bouily it is necessary only to raise member 13 to the horizontal-as in dotted lines in Fig. 1- thus permitting the internal mechanism to be raised to clear the top of the pail, the mechanism then being moved laterally to carry member 13 beneath handle leaving the pail entirely free of the mechanisml This operation is reversed when the mechanism is to be restored.

The parts are so arranged that small variations may be had in size, etc., oli pail without affecting the ability to employ the mechanism with it.

Obviously, the general principles` oi the invention are not limited to use in connection with the specific type ot mop-wringing mechanism shown. And while 1 have shown and described one way in which the invention may be carried out, it will be readily understood that changes and modifications therein may be found desirable or bc required in meeting the various exigencies of' use, and 1 desire to be understood as reserving the right to make any and all such Sil Lawson changes or modifications therein as may be found desirable or essential in so far as the same may fall within the spirit and scope ot' the invention as expressed in the accompanying claims, when broadly construed.

Having thus described my invention, what l claim as new is:
